The 87-626 is a Plano-Convex spherical lens, a type of optical lens featuring one flat and one curved surface, designed for use with a central wavelength of 1550nm. This lens is sourced from Edmund Optics, a leading manufacturer of high-quality optical components.
The lens boasts a diameter of 15.0mm and a focal length of 18.0mm, making it suitable for a variety of applications. The geometry of the lens includes a thickness of 1.4mm at the edge and 4.0mm at the center, with an effective focal length (EFL) of 18.0mm. The radius of curvature for the first surface (R1) is 12.11mm, and the back focal length (BFL) is 15.61mm.
The lens is constructed from n-SF5 Schott, a high-quality optical glass known for its excellent transmission properties in the near-infrared region. This makes the lens ideal for use in applications such as fiber optics, optical communication systems, and laser applications.
The lens features a front and back coating of EDM Las V-Coat 1550, a broadband anti-reflection coating designed for use with a central wavelength of 1550nm. This coating reduces surface reflections, improving the overall efficiency and performance of the lens.
